(Just the tip of the cardinal's wing is visible, at at 2 o'clock.) But notice that more of the scene is in the left picture. The magnification is defined by the ratio of. In the photo below, the magification is greater on the right, with 10-power binoculars. Binoculars with a higher magnification provide a larger view of objects, as well as greater resolving power. Interestingly enough, the smaller, lighter-weight 8x32 version often has the widest field of view of all.Ī wider field of view makes it easier to spot a bird among the branches or a duck on the waves. You usually get a wider field of view with an 8-power binocular than you do with the same model in 10 power. That is why many people find that they will actually see just as much detail with the lower 8-power magnification. At some point, the advantage that comes from making the image larger just gets overwhelmed by the unsteadiness of the hand. So the more you magnify, the more the image is jumping around. The binocular's magnification increases not only the size of the image, but also the apparent shakiness. Here are the ways that an 8-power binocular can give you more than a 10-power binocular.Įveryone's hands shake - a little or a lot - but no living, breathing human being has perfectly steady hands. Many expert birdwatchers insist that they see just as much detail, or even more, with an 8-power binocular as they do with a 10-power. How 8x Is more than 10x by Michael and Diane Porter Why doesn't everyone always buy 10-power binoculars? They usually cost only a little bit more than 8-power binoculars.Īt first thought, it seems as if 10 power would be better than 8x, but that's not necessarily true.
